brain-save
Saves a single fact, decision, pattern, or convention into your governed knowledge brain so it can be recalled later — and retires memories that are outdated. Side-effecting: it writes to your durable corpus, so it never auto-fires — invoke it explicitly. Use when you want the brain to remember something specific going forward without a full recompile, or to mark an old memory outdated. Trigger with "/brain-save".
Why this skill is useful
Adds a specific command for saving and governing knowledge that the AI wouldn't reliably generate on its own.
What it needs
Requires governed-second-brain, qmd installed locally. About 5k tokens when loaded. Last updated 2026-08-07. 2,604 stars on the source repository.
What this skill does
Brain Save — write a fact into your brain (governed) This is the write side of the brain. /brain reads; /brain-save writes. Use it to tell the brain to remember a specific fact going forward — without re-running a full compile — or to retire a memory that's no longer true. Overview The brain learns in two ways: a bulk compile ingests a whole corpus at once, and /brain-save adds (or retires) a single item on demand. Either way, governance stays in code: this skill captures a candidate, then runs the deterministic govern step (dedupe → policy → promotion) that decides what actually gets stored — and writes a SHA-256 hash-chained audit event for the decision. You are proposing an item for the brain to keep; the deterministic curator owns whether and how it lands. Why this never auto-fires disable-model-invocation: true means Claude will not trigger this from conversation — it runs only when you explicitly type it. Writing to your durable brain is a deliberate act, not a chat side effect. In local mode you own the brain outright — no server, token, or role; the only gate is that you asked. In team mode the same deliberate-act rule holds, and the server additionally enforces your role (a member proposes; an admin governs and retires). Prerequisites The governed-second-brain plugin is installed (it auto-wires the local governed-brain MCP server with the capture + govern tools). qmd is on your PATH so the govern step can refresh the search index after a promotion. If qmd is absent, capture + govern + the audit receipt still complete; only fresh-search visibility waits. Works in both modes. In local mode (default, no TEAMKBAPIURL) all the tools below run in-process. …
